Description

Technical Field

[0001] The utility model relates to the technical field of glasses, in particular to a pair of hingeless glasses. Background Art

[0002] Glasses generally consist of a frame, temples and lenses. The frame and temples are usually connected by fixing hinges on both the frame and the temples, and then connecting the two hinges together with screws, so that the temples can be connected to the frame and can be folded and unfolded. However, using this connection method, the screws will become loose during repeated rotation, and they will easily rust after coming into contact with sweat, affecting the appearance. Therefore, a new type of glasses is needed to solve this problem. Utility Model Content

[0003] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by implementing the utility model. The purpose and other advantages of the utility model can be realized and obtained through the structures specifically pointed out in the description and other drawings of the description.

[0004] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a pair of hingeless glasses.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is: a pair of hingeless glasses, including lenses, a frame, temples and nose pads, the temples being connected to the frame via a snap-in block, the snap-in block being provided with a ring groove, the frame being provided with a slot for the snap-in block to be embedded in, the side wall of the slot being provided with a convex ring matching the ring groove, the frame being provided with a slot for the lens to be inserted into, and after the snap-in block is matched with the slot, the portion of the ring groove that is not matched with the convex ring constitutes a part of the slot.

[0006] By adopting the above technical scheme, the cooperation of the snap-in block and the slot is utilized so that the snap-in block can be connected to the frame and integrated with the frame, which can reduce the traces of splicing and at the same time give the snap-in block a certain limit. When the snap-in block is inserted into the slot, the convex ring on the inner side of the slot will also be embedded in the ring groove of the snap-in block, further limiting the snap-in block so that the snap-in block can only slide out along the outlet of the slot. When the snap-in block is inserted into the slot, the part of the ring groove that is not matched with the convex ring will constitute a part of the snap-in slot. By snapping the lens into the slot, the snap-in block is limited by the lens while fixing the lens, thereby realizing the fixation of the limited snap-in block. When the snap-in block is fixed, the temple is also fixed. In this way, the connection between the temple and the frame can be achieved by snapping, avoiding the use of hinges and bolts.

[0007] Preferably, the temples are folded and unfolded by elastic deformation, and the temples are bent in the initial state. The utility model utilizes the bending deformation of the temples themselves to replace the function of the hinges to achieve the folding and unfolding of the temples, and through the elastic deformation of the temples, the temples can generate a certain elastic force when the temples are unfolded, and the temples can be clamped from both sides of the head when the glasses are worn, so as to adapt to different head shapes.

[0008] Preferably, the portion where the temple and the clamping block are connected has an arc transition structure. The utility model utilizes the arc transition mechanism to prevent the temple from breaking at the connection between the clamping block and the temple during the continuous bending and deformation process, thereby enhancing the overall strength of the temple.

[0009] Preferably, the clamping block has an anti-skid protrusion, and the side wall of the slot is provided with an anti-skid groove for the anti-skid protrusion to be embedded in. The utility model utilizes the cooperation of the anti-skid protrusion and the anti-skid groove to pre-fix the temples when the lens is not installed in the frame, preventing the clamping block from sliding out of the slot, facilitating the assembly of the lens, and avoiding the problem of affecting the accuracy when fitting the reading circle.

[0010] Preferably, the temple comprises an elastic deformation part and a contact part, the elastic deformation part and the contact part are connected to each other through a connecting mechanism, and the elastic deformation part is integrally formed with the clamping block. By dividing the temple into the elastic deformation part and the contact part, the contact part for contacting the skin can be made of a more skin-friendly material, thereby enhancing the wearing comfort.

[0011] Preferably, the connection structure includes a support bar, the contact portion is provided with a long hole, the support bar is fixedly connected to the elastic deformation portion, and the support bar is inserted into the long hole. The utility model inserts the support bar into the long hole of the contact portion, the long hole is curved, and both the contact portion and the support bar can be elastically deformed, so that the support bar can be inserted into the jack and is not easy to fall out, thereby achieving the connection between the elastic deformation portion and the contact portion.

[0012] Preferably, the spectacles frame is provided with a groove for inserting a nose pad, the nose pad is embedded in the groove, and the nose pad is fixedly connected to the spectacles frame via a fixing mechanism.

[0013] Preferably, the fixing mechanism comprises a screw, the screw passes through the frame and enters the groove, and the screw is threadedly connected to the nose pad.

[0014] In summary, the beneficial effects of the utility model are:

[0015] 1. The temples are fixed by means of snap-fit, slots and the cooperation of lenses. In this way, the connection between the temples and the frame can be achieved by snap-fit, avoiding the use of hinges and bolts.

[0016] 2. By using the combination of anti-skid protrusions and anti-skid grooves, the temples can be pre-fixed when the lenses are not installed in the frames to prevent the snap-in blocks from slipping out of the slots, making it easier to assemble the lenses and avoiding problems affecting the accuracy of the reading circle during fitting.

[0032] like Figure 1-4 As shown, a pair of hingeless glasses comprises a lens 1, a frame 2, temples 3 and a nose pad 4. The temples 3 are connected to the frame 2 via a snap-in block 5. The snap-in block 5 is provided with a ring groove 6. The frame 2 is provided with a slot 7 for the snap-in block 5 to be embedded. The side wall of the slot 7 is provided with a convex ring 8 matching the ring groove 6. The frame 2 is provided with a slot 9 for the lens 1 to be inserted into. After the snap-in block 5 is matched with the slot 7, the portion of the ring groove 6 that is not matched with the convex ring 8 constitutes a part of the slot 9.

[0033] When the eyeglass frame 2 is in the closed position, the eyeglass frame 2 is in the closed position, and the eyeglass frame 2 is in the closed position, so that the eyeglass frame 2 is in the closed position, and the eyeglass frame 2 is in the closed position.

[0034] The temples 3 are folded and unfolded by elastic deformation, and the temples 3 are bent in the initial state. The bending deformation of the temples 3 replaces the function of the hinge to realize the folding and unfolding of the temples 3. The temples 3 can generate a certain elastic force when the temples 3 are unfolded through the elastic deformation of the temples 3. When the glasses are worn, the temples 3 are clamped from both sides of the head, so that they can adapt to different head shapes.

[0035] The portion where the temple 3 and the clamping block 5 are connected has an arc transition structure 10. The arc transition mechanism prevents the temple 3 from breaking at the connection between the clamping block 5 and the temple 3 during the continuous bending and deformation process, thereby enhancing the overall strength of the temple 3.

[0036] The clamping block 5 is provided with an anti-skid protrusion 11, and the side wall of the slot 7 is provided with an anti-skid groove 12 for the anti-skid protrusion 11 to be inserted into. By means of the cooperation between the anti-skid protrusion 11 and the anti-skid groove 12, when the lens 1 is not installed in the frame 2, the temple 3 can be pre-fixed to prevent the clamping block 5 from sliding out of the slot 7, thereby facilitating the assembly of the lens 1 and avoiding the problem of affecting the accuracy during the fitting reading circle.

[0037] The temple 3 includes an elastic deformation portion 13 and a contact portion 14, which are connected to each other via a connecting mechanism, and the elastic deformation portion 13 is integrally formed with the clamping block 5. By dividing the temple 3 into the elastic deformation portion 13 and the contact portion 14, the contact portion 14 for contacting the skin can be made of a more skin-friendly material, thereby enhancing the wearing comfort.

[0038] The connection structure includes a support bar 15, and the contact portion 14 is provided with a long hole. The support bar 15 is fixedly connected to the elastic deformation portion 13, and the support bar 15 is inserted into the long hole. By inserting the support bar 15 into the long hole of the contact portion 14, the long hole is curved, and both the contact portion 14 and the support bar 15 can be elastically deformed, so that the support bar 15 can be inserted into the insertion hole and is not easy to fall out, thereby realizing the connection between the elastic deformation portion 13 and the contact portion 14.

[0039] The frame 2 is provided with a groove for inserting the nose pad 4. The nose pad 4 is embedded in the groove, and the nose pad 4 is fixedly connected to the frame 2 via a fixing mechanism.

[0040] The fixing mechanism includes a screw 16 , which passes through the frame 2 and enters the groove, and the screw 16 is threadedly connected to the nose pad 4 .

[0041] It should be noted that many specific details are set forth in the above description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.
